I am Eritrean and I'm going to Amsterdam from Calgary (no stops). I don't know if I need a Schengen visa, because when I went to the airport they said I need one because I'm stopping in Iceland. I cut my ticket and I'm flying a different airline and I made sure there no stops. I have tried searches but none answer my question. I have a piece of paper which says that there is someone in Amsterdam I will be staying with.
